How long do you think that Oil on this earth last?

Answer 1

it's simply hard to predict...even oil exploration experts can't define how much oil does earth holds...estimates are based on the current technology that scientist are using to determine the size of the reserves, but they admitted that it's an estimate because technologies have their limits, means that there could be more...or less.

Answer 2

Oil will exist for as long as the earth does. Peak oil enthusiasts tell us that we will run out of oil within the next 25-40 years; but those numbers relate to easily obtainable (cheap oil). When a reservoir is depleted and no more oil can be practically removed, up to half of the oil that was in the reservoir originally remains in the ground. Eventually technologies will be developed to allow some of that residue to be also extracted. The shale oil fields in Canada cannot be extracted sufficiently fast to use it all up within 25-50 years, so some production could be in place a hundred years from now. There are small pockets of oil that have been identified as uneconomic to produce, so when oil prices get to hundreds of dollars a barrel they will come on line.
In millions of years time the mouth of the Mississippi and other great rivers should be somewhere underground cooking nicely as a future oil fields. By that time, if mankind of any sort still exists, oil will probably be a long forgotten fuel and other fuels of no threat to the environment just might be in place. But as far as practical considerations are concerned the era of cheap oil is soon to be over.

Answer 3

Essentially for ever. I know this probably sounds stupid but in fact it is the only logical answer. Consider:

As oil becomes more scarce and harder (read more expensive) to recover and refine into desirable products the price will go up (why do you think it is 50-60 $/bbl instead of 20 like it was a few years ago). This will of course raise the price of fuels like gasoline and diesel.

As the price of fuels becomes more expensive, people will use less. We have already seen this in the past few years.

As the price of oil goes up alternative fuel sources become more economically attractive and will begin to replace oil.

The net result will be that we will probably never run out of oil, just cheap, easy to produce oil.

Answer 4

I don't think anybody knows. One thing we do know for sure: We were running out of oil in the 1920s. Or so people were told. We've been running out of oil ever since. Now the experts are telling us that we are close to peak production and it's down hill from here. We'll see. I don't think anybody alive today will live to see the oil get used up.

Answer 5

Too long, the longer we have oil, the more time until we get serious about alternatives. It's counter-intuitive, but having a gas guzzling car will get rid of oil faster so our children will be forced to use more eco-friendly energy sources.

Why stretch out the agony ? Get rid of the oil as fast as you can.

30-40 years tops

Answer 7

i'll give it another 50 years

Answer 8

not longer than cocaroaches do
